A fertilizing device and a top-dressing method for bamboo shoot cultivation

Abstract

The present invention discloses a fertilizing device, including a control main rod. An annular soil shoveling mechanism is installed at the bottom end of the control main rod. The annular soil shoveling mechanism includes an annular base fixedly connected to the bottom end of the control main rod. The upper surface of the annular base is fixedly connected with an annular upper shell. Both the annular base and the annular upper shell are C-shaped. By driving the conveyor belt to slide along an arc trajectory on both sides of the annular base, the soil shoveling tools on both sides are driven to move along the limiting chute to dig the soil around the bamboo shoots for fertilization. During the process of loosening the soil, the soil shoveling tools can also destroy the surrounding weeds, which helps to reduce the growth of weeds. While the soil shoveling tools move along the limiting chute, they will push the sealing component in the feeding port to open, so that the respective feeding boxes in the annular base are fed and fertilized in sequence. As the soil shoveling tools move along the limiting chute, the fertilizer is evenly scattered in the dug grooves, ensuring that the bamboo shoots can evenly absorb the required nutrients.

Description

Technical Field

[0001] The present invention relates to the technical field of plant cultivation, and particularly relates to a fertilization device and a topdressing method for bamboo shoot cultivation. Background Art

[0002] A fertilizer applicator is a machine for applying fertilizers. It consists of a fertilizer tank, a fertilizer distributor, etc., and some also have fertilizer conveying, ditch opening, and covering devices. According to the properties of the fertilizers applied, it can be divided into solid chemical fertilizer applicators, liquid chemical fertilizer applicators, manure spreaders, manure liquid spreaders, etc.; according to the different growth stages of crops, it can be divided into basal fertilizer applicators, seed fertilizer applicators, topdressing machines, etc.; according to the operation mode, it can be divided into row applicators, broadcast spreaders, deep applicators, foliar fertilizer applicators, etc.

[0003] A soil fertilization device and method for bamboo shoot cultivation disclosed in Chinese Patent CN111837547A, by arranging a stirring component in the fertilization tank to crush the fertilizer, and the sliding rods and sliding sleeves on both sides of the fertilizer tank can drive the fertilizer tank to vibrate slightly up and down, so that the fertilizer in the fertilizer tank passes through the discharge port and then is evenly sprinkled through the fertilization port, so that the bamboo shoots can obtain an appropriate amount of fertilizer and the bamboo shoots can grow well.

[0004] When the above fertilization device is used, by pushing the device above the bamboo shoots, the fertilizer will fall on the soil surface around the bamboo shoots, and the nutrients provided by the fertilizer are difficult to penetrate into the lower layer of the soil. As the bamboo shoots grow over time, it is necessary to regularly and quantitatively topdress the bamboo shoots, and fallen leaves or weeds are likely to accumulate on the surrounding soil surface, causing part of the fertilizer to be intercepted and unable to contact the soil, resulting in the roots of the bamboo shoots being difficult to absorb the nutrients of the fertilizer in the soil. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a fertilization device and a topdressing method for bamboo shoot cultivation, which have the advantages of excavating grooves along the periphery of the bamboo shoots, etc., and solve the problem that the roots of the bamboo shoots are difficult to absorb fertilizers.

[0007] (2) Technical Solutions

[0008] In order to achieve the purpose of not only solving the problem that the roots of the bamboo shoots are difficult to absorb fertilizers, but also ensuring the loosening of the soil around the bamboo shoots, the present invention provides the following technical solutions:

An annular upper shell is fixedly connected to the upper surface of the annular base. Both the annular base and the annular upper shell are C-shaped, and bamboo shoots enter and exit the annular base from the C-shaped opening. On both sides inside the annular base, there are conveyor belts. The two conveyor belts are symmetrically arc-shaped and rotate in opposite directions. An elevating component is arranged on the lower surface of the conveyor belt. A soil shoveling tool is connected below the elevating component.

During the process that the conveyor belt drives the soil shoveling tool to move along the limiting chute, the sealing components can be triggered one by one. After the soil shoveling tool excavates the soil around the bamboo shoots, it drives the passing sealing components to move so that the corresponding feeding boxes shake downwards for fertilizing.

[0015] As a preferred embodiment of the fertilizer application device of the present invention, a placement groove two is formed in the annular base. A moving groove is formed on one side of the sliding sleeve. The placement groove two and the moving groove are communicated and are slidably matched with the sliding inclined plate. A sliding inclined plate is slidably connected in the placement groove two.

[0016] As a preferred embodiment of the fertilizer application device of the present invention, the opening and closing assembly includes a buffer spring piece, a flipping cover, a coordinating gear and a mating rack. A buffer spring piece is connected to the upper surface of the material discharge box, and the end of the buffer spring piece away from the material discharge box is fixedly connected to the lower surface of the annular upper shell. A flipping cover is rotatably connected in the material discharge box. Coordinating gears are fixedly connected to both sides of the flipping cover. A mating rack is meshed with one side of the coordinating gear, and the top end of the mating rack is fixedly connected to the lower surface of the annular upper shell. A loading box is fixedly installed on the control main rod, and the loading box is connected to the annular upper shell through a hose.

[0017] As a preferred embodiment of the fertilizer application device of the present invention, a control assembly is installed at the top end of the control main rod. The control assembly includes a control frame rotatably connected to the top end of the annular base. A control grip is fixedly connected to the control frame.

[0019] The present invention also provides a topdressing method for bamboo shoot planting, which uses the above fertilization device.

[0020] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0021] 1. By driving the conveyor belt to slide along an arc-shaped track on both sides of the annular base, the earth-moving knives on both sides are driven to move along the limiting chute to dig the soil around the bamboo shoots for fertilization. Digging the soil can increase the permeability of the soil, help enhance the absorption capacity of bamboo shoots for water and nutrients, promote the healthy growth of the roots of bamboo shoots, and make the bamboo shoots located at the center of the annular base, avoiding fertilization too close to the roots of bamboo shoots, which may cause root burning of bamboo shoots. During the process of loosening the soil, the earth-moving knives can also destroy the surrounding weeds, helping to reduce the growth of weeds, reducing the competition for nutrients and water of bamboo shoots. While the earth-moving knives move along the limiting chute, they will push the sealing component in the material outlet to open, so that the respective feeding boxes in the annular base can feed and fertilize in sequence. As the earth-moving knives move along the limiting chute, the fertilizer is evenly scattered in the dug grooves, ensuring that the bamboo shoots can evenly absorb the required nutrients, which can effectively improve the growth quality of bamboo shoots more than simply fertilizing on the surface.

[0022] 2. When the earth-moving knife pushes the sliding gate block during the movement, it will drive the intercepting gate plate clamped on one side of the sliding gate block to be received into the first placement groove, so that the material outlet passed by the earth-moving knife is opened for feeding and fertilization, enabling the fertilizer to penetrate into the soil more evenly, and the roots of bamboo shoots can absorb nutrients more effectively, thus promoting the rapid growth of bamboo shoots. When the earth-moving knife passes through the sliding gate block, the compressed reset elastic piece will push the sliding gate block to slide and reset along the receiving chute under the reaction force, which can effectively reduce the overflow of fertilizer to the surrounding environment, and can more accurately control the flow rate of fertilizer, avoiding the interruption of the growth of bamboo shoots caused by too much or too little fertilizer.

[0023] 3. The buffer spring piece will push the bottom end of the blanking box to contact and impact the upper port of the blanking opening, causing the fertilizer in the blanking box to fall off from the filter plate. At the same time, the coordination gears on both sides of the top end of the blanking box will rotate along the engaged mating racks, driving the flip covers on both sides of the top end of the blanking box to open. The fertilizer stored in the loading box will be replenished into the blanking box again through the hose, ensuring that there is sufficient fertilizer supply in the blanking box during fertilization, which can effectively improve the efficiency and accuracy of fertilization, provide more balanced and continuous nutritional support for bamboo shoots, and promote their healthy growth.

Detailed implementation manners

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Embodiment 1

[0040] Refer to Figures 1-5 , Figure 9, which is the first embodiment of the present invention, provides a fertilizing device, including a control main rod 100. An annular soil shoveling mechanism 200 is installed at the bottom end of the control main rod 100. The annular soil shoveling mechanism 200 includes an annular base 201 fixedly connected to the bottom end of the control main rod 100. An annular upper shell 202 is fixedly connected to the upper surface of the annular base 201. Both the annular base 201 and the annular upper shell 202 are C-shaped. Bamboo shoots enter and exit the annular base 201 from the C-shaped opening. On both sides inside the annular base 201, there are conveyor belts 208. The two groups of conveyor belts 208 are symmetrically arc-shaped and rotate in opposite directions. An elevating assembly is arranged on the lower surface of the conveyor belt 208. A soil shoveling tool 210 is connected below the elevating assembly. A limiting chute 211 is opened on the lower surface of the annular base 201. The elevating assembly can adjust the distance between the soil shoveling tool 210 and the annular base 201. Through the operation of the conveyor belt 208, the soil shoveling tool 210 is driven to move along the limiting chute 211, and the surrounding soil is excavated by moving annularly along the bamboo shoots;

[0041] A number of uniform feeding mechanisms 300 are evenly distributed on the annular base 201. The uniform feeding mechanism 300 includes a feeding box 304 and a feeding port 301 opened on the lower surface of the annular base 201. A sealing assembly capable of pushing the feeding box 304 to shake the material is arranged in the feeding port 301. An opening and closing assembly capable of controlling the opening and closing state of the feeding port of the feeding box 304 is arranged on the feeding box 304. During the process of the conveyor belt 208 driving the soil shoveling tool 210 to move along the limiting chute 211, the sealing assemblies can be triggered one by one. After the soil shoveling tool 210 excavates the soil around the bamboo shoots, it drives the passing sealing assemblies to move, so that the corresponding feeding box 304 shakes downwards for fertilization. While the feeding box 304 moves downwards, it can drive the opening and closing assembly to open the feeding port of the feeding box 304 to load new fertilizer.

[0042] Specifically, the bamboo shoots enter into the annular base 201 and the annular upper shell 202 through the opening, so that the bamboo shoots are located at the center position of the annular base 201 and the annular upper shell 202, avoiding fertilizing too close to the roots of the bamboo shoots, which may cause the bamboo shoots to have root burning phenomenon. The elevating assembly below is driven by the conveyor belt 208 to slide in the limiting chute 211, so that the soil shoveling tools 210 on both sides move along the limiting chute 211 to dig the soil around the bamboo shoots. While the soil shoveling tool 210 moves along the limiting chute 211 to dig the soil, it will sequentially push open the sealing assemblies below the annular base 201, so that fertilization is carried out through the feeding port 301 after the soil shoveling tool 210 passes. The feeding box 304 falls and hits the upper end of the feeding port 301, so that the fertilizer is evenly distributed in the soil dug by the soil shoveling tool 210 around the bamboo shoots.

[0043] By driving the conveyor belt 208 to slide along the arc track on both sides of the annular base 201, the earth-moving tools 210 on both sides are driven to move along the limit chute 211 to dig the soil around the bamboo shoots for fertilization. Digging the soil can increase the permeability of the soil, help enhance the absorption capacity of the bamboo shoots for water and nutrients, promote the healthy growth of the bamboo shoot roots, and make the bamboo shoots located at the center of the annular base 201, avoiding fertilization too close to the roots of the bamboo shoots, which may cause root burning of the bamboo shoots. During the process of loosening the soil, the earth-moving tools 210 can also destroy the surrounding weeds, helping to reduce the growth of weeds and reduce the competition for nutrients and water of the bamboo shoots. When the earth-moving tools 210 move along the limit chute 211, they will push the sealing components in the feeding port 301 to open, and successively make the feeding boxes 304 in the annular base 201 feed and fertilize. As the earth-moving tools 210 move along the limit chute 211, the fertilizer is evenly scattered in the dug grooves, ensuring that the bamboo shoots can evenly absorb the required nutrients, which can more effectively improve the growth quality of the bamboo shoots than simply fertilizing on the surface.

[0044] Embodiment 2

[0045] Refer to Figure 5 、 Figure 6 This is the second embodiment of the present invention, providing a fertilization device. The lifting component includes a fixed sleeve 212 fixedly connected to the lower surface of the conveyor belt 208. The outer wall of the fixed sleeve 212 is slidably matched with the inner wall of the limit chute 211. The fixed sleeve 212 is in the shape of a hollow rectangle. A lifting slider 213 is slidably connected in the fixed sleeve 212. A lifting elastic sheet 214 is fixedly connected between the upper surface of the lifting slider 213 and the lower surface of the conveyor belt 208. The lower surface of the lifting slider 213 is fixedly connected with a limit slider 215. A rounded edge 216 is provided on one side of the limit slider 215, and the other side of the limit slider 215 is a vertical surface. The lower surface of the limit slider 215 is fixedly connected with the upper surface of the earth-moving tool 210.

[0046] Specifically, when the conveyor belt 208 is running in the forward direction, it drives the corresponding shoveling tool 210 to move forward along the limiting chute 211 and gradually approaches the C-shaped opening. The conveyor belt 208 drives the fixed sleeve 212 to slide in the limiting chute 211, drives the limiting slider 215 on the shoveling tool 210 to move and pushes the sealing component on one side through its vertical surface to open for fertilizing; when the conveyor belt 208 is running in the reverse direction, the conveyor belt 208 drives the shoveling tool 210 under the annular base 201 to move and reset along the limiting chute 211. When it moves in the reverse direction and contacts the sealing component, the limiting slider 215 The rounded edge 216 on one side will pass along the rounded corner on the sealing assembly, so that the limiting slider 215 drives the earth-shoveling tool 210 to descend and pull the upper lifting slider 213 to slide. The lifting slider 213 extends downward from the fixed sleeve 212 to pull the lifting spring piece 214, so that the sealing assembly slides along the upper surface of the limiting slider 215. When the limiting slider 215 passes through the sealing assembly, the lifting spring piece 214 will retract the lifting slider 213 into the fixed sleeve 212 under the reaction force. In this reciprocating manner, the earth-shoveling tool 210 slides and resets along the limiting slide groove 211 from the C-shaped opening.

When the limiting sliding column 306 slides down along the lower inclined surface of the sliding inclined plate 307 until it is completely separated from the upper surface of the sliding inclined plate 307, the discharge box 304 can fall and collide with the upper end of the discharge port 301.

[0051] Among them, the transverse chute 312 includes an upper transverse groove, an inclined groove and a lower transverse groove that are connected in sequence. The connecting parts of the upper transverse groove, the inclined groove and the lower transverse groove are all set to be arc-shaped to ensure that the movable column 311 can smoothly move along the transverse chute 312 during the movement of the sliding gate block 309; the top wall of the receiving chute 308 has the same contour as the transverse chute 312 and is parallel to it.

[0052] An intercepting gate plate 314 is slidably connected vertically in the clamping chute 313. A sliding inclined plate 307 is fixedly connected to the upper surface of the intercepting gate plate 314. A placement groove one 317 is provided in the annular base 201. The placement groove one 317 is provided on one side of the blanking port 301. One end of the intercepting gate plate 314 is slidably connected in the placement groove one 317, and a limiting push plate 315 is fixedly connected to the lower surface of the other end. One side of the limiting push plate 315 is slidably connected to the surface of the sliding gate block 309, and a reset elastic piece 316 is fixedly connected between the other side of the limiting push plate 315 and the annular base 201.

[0053] A placement groove two 318 is provided in the annular base 201. A moving groove 303 is provided on one side of the sliding sleeve 302. The placement groove two 318 and the moving groove 303 are connected and are slidably matched with the sliding inclined plate 307.

[0054] The opening and closing assembly includes a buffer elastic piece 319, a flip cover 320, a coordinating gear 321 and a mating rack 322. A buffer elastic piece 319 is connected to the upper surface of the blanking box 304. The end of the buffer elastic piece 319 away from the blanking box 304 is fixedly connected to the lower surface of the annular upper shell 202. A flip cover 320 is rotatably connected in the blanking box 304. Coordinating gears 321 are fixedly connected to both sides of the flip cover 320. A mating rack 322 is engaged with one side of the coordinating gear 321. The top end of the mating rack 322 is fixedly connected to the lower surface of the annular upper shell 202. A loading box 323 is fixedly installed on the control main rod 100. The loading box 323 is connected to the annular upper shell 202 through a hose.

[0055] Specifically, at the beginning, the sealing component closes the outlet of the discharge port 301, the intercepting gate plate 314 completely covers the discharge port 301, the sliding gate block 309 is in contact with the inner wall of the discharge port 301, and the bottom end of the limiting sliding column 306 is in contact with the plane of the upper surface of the sliding inclined plate 307 to support the discharge box 304; the conveyor belt 208 drives the corresponding earth-shoveling tool 210 to move forward, and the limiting slider 215 on the upper surface of the earth-shoveling tool 210 moves during the movement. The vertical surface of one side of the limiting slider 215 will contact the sliding plate 307. The side of the dynamic brake block 309 contacts and pushes the sliding brake block 309 to move along the receiving slide groove 308. The movable column 311 on the sliding brake block 309 first moves along the lower horizontal groove of the horizontal slide groove 312. During the movement of the sliding brake block 309, it drives the intercepting gate plate 314 connected to one side of the sliding brake block 309 to be stored in the placement groove 1 317. The limiting push plate 315 under the intercepting gate plate 314 pushes the reset spring piece 316 to compress, and at the same time drives the sliding inclined plate 307 on the upper surface of the intercepting gate plate 314 from the moving groove 317. The slot 303 slides out and moves to the second slot 318; after the bottom end of the limiting slide 306 moves from the plane of the upper surface of the sliding inclined plate 307 to the lower inclined surface, the compressed buffer spring 319 will push the limiting slide 306 at the bottom end of the discharge box 304 to slide down along the lower inclined surface of the sliding inclined plate 307 under the reaction force. When the limiting slide 306 slides off the sliding inclined plate 307, the limiting slide 306 loses the support of the sliding inclined plate 307, and the buffer spring 319 will push the bottom end of the discharge box 304 and the discharge port 304 01 contacts and collides with the upper end, causing the fertilizer in the discharge box 304 to fall from the filter plate 305, and the fallen fertilizer is scattered from the discharge port 301 into the dug groove to fertilize the bamboo shoots. When the discharge box 304 moves downward, the coordinated gears 321 on both sides of the top of the discharge box 304 will rotate along the meshing matching racks 322, driving the flip covers 320 on both sides of the top of the discharge box 304 to open, and the fertilizer stored in the charging box 323 will be replenished into the lower box 304 again through the hose;

[0056] After the movable column 311 moves to the inclined groove of the transverse chute 312, as the earth-removing tool 210 continues to move along the limiting chute 211, the limiting slider 215 will push the sliding brake block 309 to move obliquely upward until the movable column 311 moves to the upper transverse groove of the transverse chute 312. At this time, the rounded corner at the bottom end of the sliding brake block 309 rises and moves to the upper surface of the limiting slider 215 (a small rounded corner is provided at the junction of the vertical surface and the upper surface of the limiting slider 215. Under the action of the rounded corner at the bottom end of the sliding brake block 309 and the small rounded corner, the sliding brake block 309 moving obliquely upward can move from one side of the limiting slider 215 to the upper surface of the limiting slider 215). When the upper surface of the limiting slider 215 passes along the bottom end of the sliding brake block 309, the compressed reset elastic piece 316, under the reaction force, pushes the sliding brake block 309 to slide and reset along the receiving chute 308 under the sliding fit of the movable column 311 and the transverse chute 312, and the sealing component closes the outlet of the blanking port 301;

[0057] After fertilization is completed, the annular base 201 is moved away from the bamboo shoot, and the corresponding earth-removing tool 210 is driven by the conveyor belt 208 to move in the reverse direction and reset. When the earth-removing tool 210 moves in the reverse direction and resets along the limiting chute 211, since the sliding brake block 309 is attached to the inner wall of the blanking port 301, the sliding brake block 309 cannot displace along the moving direction of the limiting slider 215, and the rounded corner edge 216 on the side of the limiting slider 215 will contact the rounded corner at the bottom end of the sliding brake block 309. As the earth-removing tool 210 continues to move, the limiting slider 215 will pull the lifting slider 213 to slide downward from the fixed sleeve 212, so that the sliding brake block 309 passes along the upper surface of the limiting slider 215.
